Answers

Answer 1

Answer: Untuk menentukan modus data, kita mencari nilai yang paling sering muncul. Dalam kasus ini, tidak ada data yang disediakan, jadi tidak ada modus yang dapat ditentukan.

Untuk menentukan median data, kita mencari nilai tengah. Dalam kasus ini, kita memiliki 100 data, jadi median akan berada pada posisi ke-50. Dalam hal ini, median akan jatuh pada rentang 81-90.

4a² - 25? little help? Can you show me the steps to gets the answer? Thanks!

Answers

4a² - 25

= (2a)² - 5²

= (2a+5)(2a-5) since a² -b² = (a+b)(a-b)

This is simply a difference of squares. To factor this, you simply take the square roots of the leading coefficient and the C term. Thus you get 2 and 5. As a pair of factors, it is simply (2a+5)(2a-5). If you actually need to solve this, you can set either the factors or the original equation equal to 0.

Ebony walked at a rate of 3 1/2 miles per hour for 1 1/3 hours. how far did she walk?

Answers

Answer:

She walked $4(2)/(3)$ miles

Step-by-step explanation:

Speed of ebony = $3(1)/(2)$ miles/hour

= $(7)/(2)$ miles/hour

Time Taken = $1(1)/(3)$ hours.

= $(4)/(3)$ hours.

We are supposed to find how far did she walk i.e. Distance

Formula : $Distance = Speed * Time$

$Distance = (7)/(2) * (4)/(3)$

$Distance = (14)/(3)$

$Distance = 4(2)/(3)$

Hence she walked $4(2)/(3)$ miles
